Abstract
Description
Die Erfindung betrifft eine Luftkanalanordnung für ein Luftleitungssystem eines Flugzeugs.The The invention relates to an air duct arrangement for an air duct system of a Aircraft.
Luftleitungssysteme in Flugzeugen, etwa zur Führung von Versorgungsluft, sind üblicherweise aus einer Vielzahl hintereinander angeordneter Luftkanalrohre aufgebaut. Für eine luftdichte Verbindung aufeinander folgender dieser Luftkanalrohre ist es bekannt, eine Überwurfmanschette zu verwenden, die über die benachbarten axialen Endabschnitte der zu verbindenden Luftkanalrohre gestülpt wird und mittels Rohrschellen oder Schlauchbändern an den Rohren fixiert wird. Diese Art der Montage ist aufwendig. Zudem wird eine starke radiale Klemmkraft auf die Rohre ausgeübt, was es besonders bei Flachprofilrohren erforderlich macht, die Enden speziell auszugestalten, damit sie den einwirkenden Kräften widerstehen und das Rohr nicht zusammengequetscht wird.Duct system in airplanes, for example for guidance of supply air, are common composed of a plurality of successively arranged air duct pipes. For one airtight connection successive of these air duct pipes It is known, a cap sleeve to use that over the adjacent axial end portions of the air duct pipes to be connected inverted is fixed by means of pipe clamps or hose bands on the pipes becomes. This type of assembly is expensive. In addition, a strong radial clamping force exerted on the tubes, which is particularly true for flat profile tubes required to tailor the ends to fit them the acting forces resist and the pipe will not be squeezed together.
Aufgabe der Erfindung ist es, Luftkanalrohre eines Flugzeug-Luftleitungssystems einfacher miteinander verbinden zu können und die radialen Verbindungskräfte zu verringern.task The invention is air duct pipes of an aircraft air duct system easier to connect to each other and to reduce the radial connection forces.
Zur Lösung dieser Aufgabe ist erfindungsgemäß eine Luftkanalanordnung für ein Luftleitungssystem eines Flugzeugs vorgesehen, umfassend zwei längs einer Kanalachse mit axialem Abstand einander stirnseitig zugewandte, durch eine Verbindermanschette luftdicht verbundene Luftkanalrohre, dadurch gekennzeichnet, dass mindestens eines der Luftkanalrohre an seiner dem anderen Luftkanalrohr zugewandten Stirnseite eine in Umfangsrichtung umlaufende, stirnseitig offene Aufnahmetasche aufweist, in welche ein axialer Endabschnitt der Verbindermanschette eingesteckt ist, und dass dem in der Aufnahmetasche steckenden Endabschnitt der Verbindermanschette Dichtmittel zugeordnet sind, welche eine luftdichte Abdichtung des Endabschnitts gegenüber den Taschenwänden gewährleisten.to solution This object is according to the invention an air duct arrangement for a Air duct system of an aircraft provided, comprising two along a Channel axis with axial distance facing each other frontally, airtight air ducts connected by a connector sleeve, characterized in that at least one of the air duct pipes at its the other air duct pipe facing end side of a Circumferentially circumferential, frontally open receiving pocket in which an axial end portion of the connector sleeve is plugged in, and that in the receiving pocket end portion the connector sleeve sealant are assigned, which a ensure air-tight sealing of the end section with respect to the pocket walls.
Bei der erfindungsgemäßen Lösung ist das Einstecken der Verbindermanschette in die Aufnahmetasche mit wenig Mühe möglich. Für die Dichtigkeit der Verbindung müssen auch keine radialen Spannkräfte auf die Luftkanalrohre ausgeübt werden; die Dichtigkeit wird durch die innerhalb der Tasche befindlichen Dichtmittel gewährleistet. Besonders vorteilhaft ist die Erfindung dort, wo die Verbindermanschette keine Haltefunktion zur Stützung der Luftkanalrohre übernehmen muss, sondern allein der luftdichten Verbindung dient.at the solution according to the invention the insertion of the connector sleeve in the receiving pocket with little effort possible. For the Tightness of the connection must also no radial clamping forces exerted on the air ducts become; the tightness is due to the inside of the bag Ensures sealant. The invention is particularly advantageous where the connector sleeve no holding function for support take over the air duct pipes must, but only the airtight connection is used.
Die Dichtmittel können beispielsweise einen radial innen und radial außen an den Taschenwänden anliegenden Dichtring umfassen, welcher auf den Stirnrand des in der Aufnahmetasche steckenden Endabschnitts der Verbindermanschette aufgesetzt ist und so den Stirnrand radial innen und außen umgreift. In diesem Fall kommt man mit einem einzigen Dichtring pro Tasche aus. Alternativ ist es vorstellbar, radial beidseits des in die Tasche ragenden Manschettenendabschnitts je einen Dichtring vorzusehen. Als Dichtring kann beispielsweise ein O-Ring oder ein Lippendichtring verwendet werden. Ein solcher Dichtring kann abnehmbar auf die Verbindermanschette aufgesetzt oder in die Tasche eingesetzt sein oder er kann fest mit der Manschette oder der Tasche verbunden sein, etwa durch Kleben oder Schweißen. Denkbar ist es auch, ein oder mehrere einstückig mit der Verbindermanschette oder der Tasche ausgeführte Dichtelemente, etwa in Form eines umlaufenden Dichtwulstes, vorzusehen.The Sealants can For example, a radially inwardly and radially outboard of the bag walls Include sealing ring, which on the front edge of the in the receiving pocket plugged end portion of the connector sleeve is placed and so surrounds the end edge radially inward and outward. In this case to get out with a single seal per bag. alternative it is conceivable, radially on both sides of the protruding into the pocket sleeve end portion each to provide a sealing ring. As a sealing ring, for example an O-ring or a lip seal can be used. Such a Sealing ring can be detachably mounted on the connector sleeve or put in the bag or he can be firm with the cuff or the bag be connected, such as by gluing or welding. Conceivable It is also one or more integral with the connector sleeve or the bag executed Provide sealing elements, such as in the form of a circumferential sealing bead.
Die radial innere/oder und die radial äußere Wand der Aufnahmetasche kann mit einer gewissen radialen Flexibilität ausgeführt sein.The radially inner / or and the radially outer wall of the receiving pocket can be designed with a certain radial flexibility.
Zweckmäßigerweise weist jedes der beiden Luftkanalrohre eine Aufnahmetasche auf, in welche die Verbindermanschette mit je einem ihrer axialen Endabschnitte eingesteckt ist.Conveniently, has each of the two air duct pipes on a receiving pocket, in which the connector sleeve, each having one of its axial end portions is plugged in.
Um Relativbewegungen in axialer oder/und in radialer Richtung zwischen den beiden Luftkanalrohren zu ermöglichen, ist es vorteilhaft, wenn die Verbindermanschette in einem axialen Bereich zwischen den beiden Luftkanalrohren mindestens eine Balgenfalte aufweist. Dabei kann die Verbindermanschette beispielsweise insgesamt eine oder insgesamt zwei Balgenfalten aufweisen. Es versteht sich, dass alternativ auch mehr als zwei Balgenfalten vorhanden sein können. Die mindestens eine Balgenfalte kann etwaige relative Längsbewegungen, Winkelbewegungen und Bewegungen, die einen Achsversatz der beiden Luftkanalrohre verursachen, kompensieren. Solche Bewegungen können durch unvermeidliche Vibrationseinflüsse hervorgerufen werden, aber auch durch temperaturbedingt sein. Der Manschettenbereich zwischen den Luftkanalrohren kann dabei elastisch biegsame Materialien umfassen, z. B. ein Textilmaterial, einen Kunststoff oder/und einen Gummiwerkstoff.Around Relative movements in the axial or / and in the radial direction between to enable the two ducts, it is advantageous when the connector sleeve in an axial region between the has at least one bellows crease both air ducts. there For example, the connector collar may be one or all have a total of two bellows folds. It is understood that alternatively also more than two bellows folds can be present. The at least one bellows fold can be any relative longitudinal movements, Angular movements and movements, the axis offset of the two Cause air ducts to compensate. Such movements can through unavoidable vibration influences be caused, but also be due to temperature. Of the Cuff area between the air duct pipes can be elastic flexible materials include, for. As a textile material, a plastic and / or a rubber material.
Für ein erleichtertes Einschieben der Manschette in die Aufnahmetasche ist die Verbindermanschette in einem axial außerhalb der mindestens einen Balgenfalte liegenden Bereich bevorzugt verformungssteifer ausgeführt als im Bereich der mindestens einen Balgenfalte. Dabei kann die Verbindermanschette axial außerhalb der mindestens einen Balgenfalte wenigstens eine umlaufende Aussteifungslage aufweisen, etwa in Form einer Gewebelage ausreichender Steifigkeit oder einer metallischen oder zumindest einen Metallwerkstoff enthaltenden Einlage. Eine solche Aussteifungslage kann in die Manschette eingebettet sein oder außen aufgelegt sein. Alternativ oder zusätzlich kann die Verbindermanschette axial außerhalb der mindestens einen Balgenfalte wenigstens eine außen aufgesetzte, in Umlaufrichtung verlaufende Winkelleiste aufweisen. Eine solche Winkelleiste kann auch zur Begrenzung der Einstecktiefe der Verbindermanschette in die Aufnahmetasche dienen.For a simplified insertion of the sleeve into the receiving pocket, the connector sleeve is preferably made more resistant to deformation in an area lying axially outside the at least one bellows fold than in the region of the at least one bellows fold. In this case, the connector sleeve axially outside the at least one bellows fold at least have a circumferential stiffening position, such as in the form of a fabric layer sufficient rigidity or a metallic or at least one metal material-containing insert. Such a stiffening layer can be embedded in the cuff or placed outside be. Alternatively or additionally, the connector sleeve axially outside of the at least one bellows fold at least one externally patched, extending in the direction of rotation angle bar. Such an angle bar can also serve to limit the insertion depth of the connector sleeve in the receiving pocket.
Die Verbindermanschette ist gemäß einer bevorzugten Ausführungsform wenigstens teilweise aus einem Gewebematerial gefertigt. Beispielsweise kann es sich hierbei um ein ein- oder mehrlagiges textiles Geflecht aus einer Kunst- oder Naturfaser handeln.The Connector sleeve is according to a preferred embodiment at least partially made of a fabric material. For example, can this is a single or multi-ply textile mesh an artificial or natural fiber.
Die Luftkanalrohre können Flachprofilrohre sein, beispielsweise mit einem Querschnitt von mindestens 450 × 130 mm oder größer. Die Erfindung ist freilich gleichermaßen anwendbar bei Rohren mit einer anderen Profilform, insbesondere auch bei Rohren mit Kreisquerschnitt.The Canals can Be flat profile tubes, for example with a cross section of at least 450 × 130 mm or larger. The Of course, the invention is equally applicable to pipes with another profile shape, especially for pipes with circular cross-section.
Die Erfindung wird nachfolgend anhand der beigefügten Zeichnungen näher erläutert. Es stellen dar:The The invention will be explained in more detail with reference to the accompanying drawings. It represent:

Die erfindungsgemäße Luftkanalanordnung für ein Luftversorgungssystem eines Flugzeugs, wie sie oben beschrieben wurde, ermöglicht ein schnelles Verbinden und Trennen der beteiligten Luftkanalrohre. Die Verbindermanschette muss lediglich aus der Aufnahmetasche eines der Luftkanalrohre herausgezogen werden, um die Verbindung zu trennen, bzw. in die Aufnahmetaschen der beteiligten Luftkanalrohre eingesteckt werden, um eine luftdichte Verbindung herzustellen. Durch die Komprimierung der Dichtmittel in den Aufnahmetaschen wird die Verbindermanschette durch Kraftschluss bzw. Reibschluss an den Luftkanalrohren gesichert.The air duct arrangement according to the invention for an air supply system of an aircraft, as has been described above, enables a quick connection and disconnection of the air duct pipes involved. The connector sleeve must only off the receiving pocket of one of the air duct pipes are pulled out to disconnect the connection, or are inserted into the receiving pockets of the air duct pipes involved to make an air-tight connection. By compressing the sealant in the receiving pockets, the connector sleeve is secured by traction or frictional engagement on the air duct pipes.
In Rütteltisch-Versuchen wurde bestätigt, dass diese Sicherung den Anforderungen und Vorschriften für Verbindermanschetten von Luftversorgungssystemen in Flugzeugen genügt und keine weiteren Sicherungsvorkehrungen getroffen werden müssen, um die Verbindermanschette an den Luftkanalrohren zu sichern. Insbesondere ist die Verwendung von Rohrschellen oder Schlauchbändern zur Sicherung der Verbindermanschette nicht notwendig. Da keine Rohrschellen oder Schlauchbänder verwendet werden, verringern sich die an den Endabschnitten der Luftkanalrohre wirkenden Kräfte deutlich. Die Rohre müssen deshalb im Wesentlichen in ihrem Anschlussbereich nicht besonders ausgeformt sein, z. B. zum Erzeugen einer Balligkeit, oder besonders verstärkt sein. So können auch Kosten und Gewicht gespart werden.In Shake table experiments it was confirmed that This fuse meets the requirements and regulations for connector sleeves of air supply systems in aircraft and no further safeguards have to be taken to secure the connector collar to the ducts. Especially is the use of pipe clamps or hose bands to secure the connector sleeve is not necessary. Since no pipe clamps or hose bands are used, the decrease in the end sections of the Air duct pipes acting forces significantly. The pipes need therefore, in essence, not particularly in their connection area be formed, z. B. for generating a crown, or especially reinforced be. So can also costs and weight can be saved.
